From the perspective of consumer behaviour, the popularity of noise-cancelling headset with mic in recent years is closely related to the social environment, user mentality and consumption level. Under the huge pressure of life, noise-cancelling headsets are a safe haven for many people. Just put on the headsets, activate the noise reduction button, and enjoy the favourite music in a quiet environment, which is a kind of relaxation after busy work. The comfortable use scene, coupled with a noise cancelling headset with mic effectively blocking the noise in office or travel scenes, is the driving force that many people buy noise cancelling headsets with mic.
Active noise cancelling headset with microphone is seemingly born to create a quiet listening environment for us. Is this created for us to better appreciate music? In fact, noise-cancelling headsets with mic were built for a deeper goal - to protect hearing. Excessive noise has a great influence on the reproduction of music details. This is due to the masking effect of the sound: although all sounds will enter our ears, if there is a stronger sound and a weaker sound at the same time, we will feel the stronger sound is clearer and the weaker sound will be masked. To put it simply, although both the stronger sound and the weaker sound exist, and the weaker sound does not disappear in the presence of the stronger sound, but is covered up, causing a false impression of "hearing" that the weaker sound is inaudible.
Because of the sound masking effect, many people can lower the volume of the earphones when listening to music in the middle of the night. If you need to listen to music outdoors in a noisy environment, you need to adjust the volume of the earphones higher. Many people like to wear earphones to listen to music when taking public transportation, which can not only kill the boring time on the road but also effectively isolate the noise from the outside world. Due to the need to isolate external noise, many people not only use in-ear headsets but also turn the volume relatively high. If you choose a flat-head plug, the volume may be turned on a little bit higher. It feels good to be surrounded by music in your ears, but if you are exposed to this condition all year round, it will easily damage your hearing. In this circumstance, a wired headset with noise cancelling microphone is suggested to use.
Generally speaking, the volume of a commuter vehicle will be around 50~80 decibels. To hear the sound from the earphone in such a loud noise environment, the volume of the earphone needs to be adjusted sufficiently. If the continuous use time is too long (generally more than 1 hour even if listening to music for a long time), and repeated every day, it will have a certain impact on hearing. With the hazards of listening to music at high volume for a long time gradually surfaced, both manufacturers and consumers have turned their attention to corded noise cancelling headphones.
